GEORGE STEGK AND FRANKLIN ARNOLD, OF HUGHESVILLE, PENNSYLVANIAIMPROVEMENT EN PUMPS.

Specification forming part of Letters Patent No. 121,016, dated November14, 1871.

To all whom it may concern:

Be it known that we, GEORGE Srncx and FRANKLIN ARNOLD, both ofHughesville, in Lycoming county and State of Pennsylvania, have inventedan Improved Pump; and We do hereby declare the following to be a full,clear, and exact description of the same,reference being. had to theaccompanying drawing forming part of this specification, in which-Figure l is a vertical section; Fig. 2, a side elevation, showing theupper part of the apparatus Fig. 3, a section, showing-the method ofconnecting the racks and plunger-rods; Fig. 4, a side view of the box,with a portion of the wall broken away to reveal the internalconstruction; Fig. 5, a horizontal section of the box in line 00 m ofFig. 4; and Fig. 6 is a section in line 3 3 of Fig. 2.

Similar letters of reference in the accompanying.

drawing indicate corresponding parts.

Our invention,- although in many respects adapted to all classes ofhand-pumps, relates particularly to that classin which the water israised by atmospheric pressure, and the main principles of the inventionare applicable either to rais-. ing water from shallow wells or fromdeep ones, where it has to be elevated from one point to another bysuccessive relays or stages. The invention consists, first, in apump-box and valve of novel construction; second, in a new arrangementof the parts for working the plunger uniformly in a perfectly verticalline and so as to economize power; and thirdly, in the generalcombination of parts constructed as herein set forth.

In the drawing, B indicates the box, which may be either round orsquare, according to the form of the pump-barrel. Whether round orsquare, it is constructed or cast with two side pieces, I) I), connectedat their upper ends by a d1ametrical cross-bar, I), which receives theplungerrod P, and also serves to support the valves V V, the two sides bI) being separated by a space, 0 0, where their edges approach eachother, and by a wider space inside of the points 0 0, so that the watercan pass freely up on both sides of the cross-piece I), from saidcross-piece to the wall of the pump. At the same time provision is thusmade for the proper support of the valves,

both at their hinges and around their edges, at every point except thespace 0 0. The upper surface of the cross-bar b is on a level with theupper edge of the walls I) I) at the openings 0 0; but between thosepoints the metal is cut away, as shown along the lines 0 6, so as topartially countersink the valves, and at the same time cause them to sitin an inclined position, whereby they lift easily when the box isdescending, and also wedge closely down against the wall of the pump andform a water-tight joint when the box is ascending. The valve consistsof two pieces, 21 o, of wood or metal, (nearly semicircular in roundpumps,) which fit closely down upon the box, as shown in Fig. 4, and aresupported by a nearly circular piece, 0, of leather, rubber, or otherequivalent flexible material, riveted or clamped by a bar, n, upon thecross-piece b. The edges of this leather strip are cut so as to flareoutward from their lower to their upper surface, as

shown in Fig. 4. The clamping-bar or plate it may be fastened down uponthe leather by rivets, or by a screw-nut or collar around theplunger-rod, as shown at i, or in any other suitable manner. Theconstruction of box and valve here shown and described dispense with allsuperfluous weight of material, yet renders the box steady in itsmovement, enables the water to act with full leverage in raising thevalves, and yet allows the valves when the box is rising to spreadagainst the wall of the pump, forming a tight joint, as above described.The whole can be readily constructed, and when necessary to repair thevalves in any way they can be readily taken out and readjusted, or newones substituted, by anybody, however inexperienced in such matters. Thebox and valve thus constructed are to be used in the ordinary way inshort single-barrel pumps where the draught is less than thirty-threefeet; but where, it is over that distance we connect a pump-stock, G,some thirty feet in length, to a vessel, A, which is divided into twocompartments by a partition, to,

extending nearly to its top. We pump the water up into one compartment,letting it run over into the other, which is open to the air. We setanother pump stock, G, in this compartment, which lifts the watertherefrom thirty feet more and pours it into another vessel similar tothat at A, from which it is again raised another stage, and so on to anyrequired height.

The means which we employ for operating the plunger-rods or series ofplunger-rods connected with the difi'erent stages are as follows: Weattach a couple of guide-standards, F F, to the pump-cover or frame, andconnect them by crossbars H provided with journal-boxes h at theircenter. In the guides we place vertical racks It R having lateralflanges r 1', which hold them true to a vertical line. The two racks areconstructed with an enlarged lower end, 7", having a recess in the rearside and a straight hole directly through from the recess to their frontside, as shown in Fig. 3. The upper ends of the plunger-rods are bent toa right angle or a hook, as there shown, and inserted from the rear sideof the racks, so that, when the latter are lowered into the guides afterbeing thus connected, the guideflanges r 0" keep the racks in place, andthe top of the plunger-rod being confined between the wall of theguide-groove and the rear side of the racks, cannot become detached norwork loose, although they are not bolted nor otherwise fastened to theracks. To detach the parts, it is only necessary to lift the racks highenough to bring the shoulders of the plunger-rods above theguide-standards, when they come apart without diificulty. The racks,which thus rise and fall in a perfectly vertical line so as to wear thepump-boxes vertically with little friction, are both operated inopposite directions alternately by means of a cog-wheel, W, of peculiarconstruction, supported on a shaft which bears in the boxes h h, andgearing with both racks, as shown in Figs. 1 and 2. The

. power is applied to the wheel W by means of a vertical lever, L, thelower end of which is divided so as to embrace both faces of the wheel,as shown in Figs. 2 and 6. To this end the series of cogs on the wheelare interrupted by a socket, which consists of arecess formed in eachside of the wheel, and bounded laterally by projecting flanges s s. Themetal of the wheel between the flanges is only about half or one-thirdthe thickness of the wheel elsewhere, in consequence of the recessesbeing formed on each side, as above described. The divided handle isslipped upon this thin plate of metal and driven into place till thewood wedges firmly between the flanges s s and the end of the slot inthe handle rests against the rim of the wheel. One or more rivets, t,are then inserted through the handle and thin part of the wheel, asshown in Fig. 2, and when the attachment is perfected a strong anddurable connection is made between the handle and wheel, which is notliable to get out of order in any way.

My object in thus constructing the wheel W is to adapt it to receivingand firmly holding a vertical handle, L, while the wheel is in gear witha rack, R, on each side. This adapts it to this form of double pump andto the use of a vertical lever for operating the same, whereby apeculiar advantage is obtained, for with a horizontal lever one plungermust be lifted by main strength, the weight of the body not being thrownupon it, an exertion which is exceedingly arduous; whereas, with theupright lever, the weight of the body can be brought against or upon itin either direction, and therefore one plunger can be raised as easilyas the other. In a single pump, where only one rack is used with thewheel, the horizontal lever may be employed, the construction of thewheel and its socket adapting it as well to one form of pump as another,and obviating the necessity, at the manufactory, of making one set ofcastings for single and another for double pumps.

Having thus described our invention, what we claim as new therein, anddesire to secure by Letters Patent, is

The relay-pump herein described, consisting of the stocksGr G, the openvesselA divided into two compartments, as described, the boxes andvalves herein described, the plunger-rods P P, the racks R It, theguides F F, the wheel W constructed with the socket, as described, andthe vertical handle L, all arranged and operating in connection witheach other substantially as herein set forth.
